Dynamic stability and reform of political institutions

This paper examines endogenous institutional change in a class of dynamic political games. The political aggregation rules used at date t+1 are instrumental choices under rules at date t. Effectively, rules are “players” who can strategically delegate future policy-making authority to different rules. A political rule is stable if it selects itself. A reform occurs when an alternative rule is selected. The stability of a political rule is shown to depend on whether its choices are dynamically consistent. For instance, simple majority rules can be shown to be dynamically consistent in many common environments where wealth-weighted voting rules are not. The result extends to political rules that incorporate private activities such as extra-legal protests, threats, or private investment. The approach is one way of understanding various explanations of institutional change proposed in the literature. A parametric model of public goods provision gives an illustration.     

Homogeneous middleman groups as superorganisms,endogamous ethnic groups,and trust networks: Reply to comments on Janet Landa’s target article, ‘The bioeconomics of homogeneous middleman groups as adaptive units’

This article responds to some of the very valuable comments on my target article (Landa, J Bioeconomics 10(3):259–278, 2008) on homogeneous middleman groups (HMGs) as adaptive units. In addition to viewing HMGs as adaptive units, I discuss the idea of viewing HMGs as superorganisms and as endogamous ethnic groups, as well as re-emphasizing the importance of HMGs as trust networks. My theory of HMGs as adaptive units shares some similarities with biologists’ ‘biological market theory’ of mutualistic interactions between species.      

Legislators' behaviour and electoral rules: Evidence from an Italian reform

We explore how electoral rules and the degree of civicness of the voters interact in shaping elected officials' behaviour. We examine the expenditure proposals sponsored by Italian Senators from 1994 to 2013 and exploit the 2005 electoral reform that transformed a mainly majoritarian system into a mainly proportional one. First, we find that legislators elected in first-past-the-post districts are more likely to sponsor pork-barrel bills and to put effort into legislative activity than those elected with a closed-list proportional system. Second, more importantly, we show that the effects of the electoral rules are muted in areas with high civicness.     

Fiscal policy in the US: Sustainable after all?

The sustainability of US public debt has been widely discussed since the Great Recession. Using annual data since 1940, we estimate and compare different specifications of fiscal rules. Estimates of constant-parameter fiscal rules show no evidence of sustainability. This may be due to the instability of government's behaviour over time. Thus, we estimate a Markov-switching fiscal rule in order to identify periods of unsustainable and sustainable fiscal policies. First, we show that the government stabilizes public debt only periodically. Second, during these periods, the government's reaction is sufficiently tight to stabilize public debt over the entire horizon. We conclude that a relatively short-lived but tight fiscal contraction can be sufficient to ensure long-run US debt sustainability.     

Stock market uncertainty and interest rate behaviour: a panel GARCH approach

Using a dynamic panel GARCH model for Asian countries, we find that interest rates are significantly lower when stock market uncertainty is high. Evidence of a positive relationship between stock market uncertainty and interest rate volatility is also provided.     

The exchange rate and optimal monetary policy rules in open and developing economies: Some simple analytics

Using a simple, tractable model, this paper revisits and expands upon issues relating to optimal monetary policy rules (MPRs) in open economies. The optimality of the rule is explored through various specifications of a central bank loss function as it is the loss function that offers insight into central bank preferences. Many of the issues on this topic have centred on the role of the exchange rate: Is it optimal for the policy instrument to react to the exchange rate? What is the role of the exchange rate in a domestic inflation targeting vs CPI inflation targeting? Does a fear of floating have any bearing on the way optimal MPRs are constructed? While this paper is not empirical, the analysis is relevant for central banks in open and developing economies that face a choice between allowing exchange rates to float (and adopting an inflation targeting regime) and engaging in some degree of exchange rate fixity.

Theoretical conditions under which monetary policies are effective and practical obstacles to their verification

Summary. We derive (i) necessary and sufficient and (ii) sufficient conditions for monetary policies to conform to what the literature characterizes as good policies. We show that the biasing effects of omitted variables, measurement errors, and misspecifications of true functional forms on the coefficients of monetary-policy reaction functions present practical obstacles to verifying such conditions.Received: 30 September 2003, Revised: 6 February 2004, JEL Classification Numbers: E52, E58.
